76 UnAuthPrincipal means that it is not coming from the official Authorization chain.
77 This is useful for Security Plugins which don't use Principal as the tie between
78 Authentication and Authorization
80 You can also use this if you want to check Authorization without actually Authenticating, as may
81 be the case with certain Onboarding Tooling.

94 * so the call is not expensive.
96 * Note: If you are using "J2EE" (Servlets), CADI ties this function to the method:
97 * HttpServletRequest.isUserInRole(String user)
99 * The J2EE user can expect that his servlet will NOT be called without a Validated Principal, and that
100 * "isUserInRole()" will validate if the user has the Permission designated.
